Unpick completed picking list from Transfer Order with Shipped status
Thanks Jones!
Below is not entirely true and the article has to be corrected specifically on the last note paragraph.
"Use the 'Cancel Transfer Order' feature. Notice this is for the entire order, you will have to process the other lines again."
Each transfer order line can be reserved, picked and/or shipped individually. Therefore, only items included in the shipment will be impacted and has to be processed again starting from reservation.
